Abstract

This study aimed to evaluate the antibacterial, physicochemical, and mechanical properties of pit and fissure sealants containing different weight percentages of zinc oxide nanoparticles (ZnO NPs). The following amounts of ZnO NPs were added to a commercially available pit and fissure sealant (BeautiSealant, Shofu, Japan) to prepare the experimental materials: 0 wt.% (commercial control (CC)), 0.5 wt.% (ZnO 0.5), 1 wt.% (ZnO 1.0), 2 wt.% (ZnO 2.0), and 4 wt.% (ZnO 4.0). The antibacterial effect against was confirmed by counting the colony-forming units (CFUs) and observing live/dead bacteria. In addition, ion release, depth of cure, water sorption and solubility, and flexural strength tests were conducted. When compared with the CC, the experimental groups containing ZnO NPs showed zinc ion emission and significantly different CFUs ( < 0.05) with fewer live bacteria. ZnO NP addition reduced the depth of cure and water solubility and increased water sorption in comparison with the CC ( < 0.05). However, all groups showed similar flexural strength ( > 0.05). The pit and fissure sealants containing ZnO NPs exhibited antibacterial activity against with no negative effects on physicochemical and mechanical properties, and thus, these sealants can be ideal secondary caries prevention material.

摘要

本研究旨在评估含有不同重量百分比氧化锌纳米颗粒（ZnO NPs）的窝沟封闭剂的抗菌、物理化学和机械性能。将以下数量的ZnO NPs添加到市售窝沟封闭剂（BeautiSealant，日本松风）中以制备实验材料：0重量%（商业对照（CC））、0.5重量%（ZnO 0.5）、1重量%（ZnO 1.0）、2重量%（ZnO 2.0）和4重量%（ZnO 4.0）。通过计算菌落形成单位（CFUs）和观察活菌/死菌来确认对[具体细菌名称未给出]的抗菌效果。此外，还进行了离子释放、固化深度、吸水性和溶解性以及弯曲强度测试。与CC相比，含有ZnO NPs的实验组显示出锌离子释放，并且CFUs有显著差异（P<0.05），活菌数量更少。与CC相比，添加ZnO NPs降低了固化深度和水溶性，并增加了吸水性（P<0.05）。然而，所有组的弯曲强度相似（P>0.05）。含有ZnO NPs的窝沟封闭剂对[具体细菌名称未给出]具有抗菌活性，且对物理化学和机械性能无负面影响，因此，这些封闭剂可以成为理想的继发性龋齿预防材料。
